Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed May 13, 1810: Serial No. 581,088.

It all whom "it may concern:

Be it known that I, LEWIS E. Arizona, a citizen of the United States, residing at Honolulu, in the county of Honolulu, Terrltory of Hawaii,- hnve invented certain new and useful Improvements in Machines 'for A further object is w a.) wa with all revolving site, such as are used in machines here fore employed for this urpose. This invention contemplates a raine, 'a. head agsinst which one end of the fruit to be treated is centered, a. stripper, and a. head- ;provided with a. coring tube and with a. sizing tube and with means r, partin the rind, all as hereinafter il'tle ed on claimed.- The novel construction f the siz-. ing knife as contemplated by this invention makes its unnecessary to revolve either the sizin tube or the fruit.

This specification is a specific description if one form" of the inventionwhile the claims are definitions of the ectual scope thereof.

Fig, 6 is an enlarged view of a development of art of the cutting end of the sizing tube.- V ig: 7 is a modification of Ifig. 6; Big: 8is w flan View. of a modification bed or frame of the mnby suitable legs 2.- ortedet oneend of 1 represents the thefisine 1; is provid sh 32,1:1' recess 8" being *1 v .1

of the invention illustreted- Fig.-4 shows a,

cutting edge 0 with shoes 3' a formed between said boss rind ring. A pin 4: or the like is secured in the center of the boss 3", on which one end of the fruit to be trentedis centered.

The movable head 5 is provided with o ton us 5 which fits a longitudinal slot 1 1n t-e frame 1, and e plateor washer 6 is bolted to the head 5 under the frame 1'by' the bolt 7, such that the head 5 m'ay'slide' upon the frame 1 between the stops 1' and 1. The curved upper portion 5* of the head 5 receives the rear end of'the sizing tube 8 and the bolts 9 fasten same together. The

head 5 is also provided with an arm 5", in

which the coring tube 10 is adjustebly secured b a set screw 11, A handle 12 may be provided for operatin the sliding head 5.

Knives 13,1)1'eferablyo theVsha, shown, are formed on the cutting end of t e sizing tube 8, four bcingillustrwtedl It will be noted thaton cutting edge 13 of sec knife 13 is made longer than the cutting ge "13 on them dsite side of the Y, an that 'a portioh o the edge13 extendsrearward as Well as laterally with"respect-to the Indiecent cutting edge '13", withfaslot 313 between them, clearly shown in 6, and such that a, portion of theed'e 13* crosses the path of a portion of the e i'ge' 18", when the sizing tube 8 is moved forward or toward the head. 3, this bein done to insure that the fruit may be comp etely sized, and not leave sportion of the fruit or fibers of some uncut, as would ptherwiseroccur sit the bottom of the crotch formedbetween';adja.-

cent V shaped knives-if bothciittingedges. were made alike and met in the crotch.

Both cutting edges are inclined tothe -lon'gi tudina-l axis of the sizing tube togi a shearing cut. n

In the modification shown in Fig. 7,"- each knife is provided with only 'one cuttiiiiledge, inclined to the longitddinel alzgis of t e sizing tube, and a. ortion of each knife extends rearward laterally end'bsck of the l the qyacent knife in the crotch formed betweeiythe'lmwes, for the previou" "described. In this case, owevsr, enc'y'. to revolve. the ru1t." A 'finf shaped knife or wedge 14 is secured to the outslde of the sizing tube 8 .amng

pass freely, is attached to he er. of a bar 16. The diameter of the stripper plate 15 18 such that the sizing tube 8 may pass over and clear same. The bar 16 is adjustably supported, by the set screw 18 in the bracket 17 secured to the rear end of the frame 1. The ring 3 of the stationary head 3, agamst which one end of the fruit abuts, is made small enough to clear the knives Iii. The recess 3 is provided to admit the cuttlng end of the corin tube 10. If desired the cuttin end of tie coring tube may be (provided wit 1 knives of the same style as for the sizin tube 8. The forward or cutting end of t. e coring tube 10 is preferably in advance of the knives 13 of the sizin tube 8, for the purpose of centering the en of the fruit by the core and not by the outside of the fruit.

In the modification shown in Fi 8, the sizing tube 8 is expanded just bac of the knives 13, the object being to force asunder the outer ortion of the fruit cut by the knives and cause same to fall away from the sizin tube 8. If desired, a knife 14 may be added.

It is obvious that various modifications may be devised without departing from the invention, for example, the head 5'with coring tube 10 and sizin tube 8 could be made the stationary mem er and the head 3 made the movable member, the stripperln this case being supported by the movable member. Of course more't an pne knlfe In operation, the osition of the strip or plate 15 is adjusted to admit a fruit etween the point of the in 4 and said striper, the ends of the fruit preferably having can cut oil. The fruit is then centered hand and forced on the pin 4. Themovab e head 5 being in its rear position is now slid forward, brin the cuttingend of the coring tube 10 throu h the hole 15 in the stripper. late15 an up to the end of the is end of the fruit is now moved b hand to bring the core concentric with tlie coring tube 10. The head 5 is then moved forward to the stop 1, and in so doing the corin tube has been passed through the fruit an into the recess 3", the boss '8 entering the coring tube 10. At the'same time the knives 13 have completely passed through the fruit and are now outslde of the the ives 13 have cut the fruit with a shearing cut to the desired size, and the fin knife 14 has cut the rind longitudinally and er- 3 which has entered the sizing tube 8;.

mitted the portionof the fruit outside '0 the siz' "tube 8 to fall away from the latter. cniiii sad 5 is nowreturned to its former sition age t the etc 1'' withdraw the coring tube 10 (wi th s corejnsid g from the fruit, and at the same time the tube 8 has been the escribed fruit by the interference of the stripper 15. The fruit has thus been cored, peeled and sized, and the operation is repeated with the next fruit. The cores are forced out through the rear end of the coring tube 10 by the succeeding cores.
